The existing regulatory reporting platform was built on a legacy DB2-based data warehouse environment that had evolved over many years through incremental developments and growing regulatory requirements. Over time, the platform became increasingly difficult to maintain due to complex data flows, redundant reporting logic, unused reports, and fragmented data structures. In addition, long-running batch processes, limited scalability, and increasing operational dependency created challenges for adapting to new reporting requirements and ensuring sustainable platform governance. The organization also needed stronger reconciliation capabilities between regulatory outputs and General Ledger (GL) balances to improve consistency, traceability, and audit readiness.
CALIGO led a comprehensive regulatory reporting replatforming and modernization initiative, migrating the existing environment from DB2 to an Oracle Exadata-based architecture designed for high-performance analytical workloads. As part of the transformation program, CALIGO: Performed end-to-end analysis of the existing regulatory reporting landscape Identified actively used, obsolete, and redundant reports Redesigned and simplified the centralized regulatory reporting data model Re-engineered reporting processes and dependencies for improved maintainability Established a dedicated GL reconciliation solution to strengthen financial consistency controls Optimized ETL and reporting workloads for Oracle Exadata architecture Conducted detailed business validation sessions for redesigned reports Managed business approval and regression validation processes for all redesigned outputs The project also introduced a more governed and sustainable reporting architecture with improved transparency, operational monitoring, and traceability across reporting layers.
The modernization initiative enabled the organization to transition from a legacy reporting infrastructure to a scalable, high-performance Oracle Exadata platform capable of supporting future regulatory and analytical needs. The redesigned reporting architecture reduced operational complexity, improved maintainability, strengthened reconciliation capabilities, and provided a more transparent and governed reporting ecosystem. The organization also gained a cleaner and more sustainable centralized data model aligned with current business and regulatory requirements.
